I have a Berlingo Multispace XTR and yesterday my son was messing with the fuel cap whilst we opened the sliding door. My wife went to close the fuel cap while at the same time was in the process of opening the door. She said she felt resistance when shutting the cap but she closed it anyway. Now the door will only slide open a couple of mm and Jams. Its as if the lock on the door is still engaged.

Hello Jamie welcome to the forum there is a safety device to stop you opening the door when the filler cap is off when she forced the filler cap on she may of broke it the first thing to do shut the door take the filler cap off and put it back on then try the door the sensor may be damage and need replacing i'm not sure if it's in the cap or the flap that open's .
